I GERHARD JOAN OTTO DORIS DIKKERS, OF LONNEKER, NEAR HENGELO,NETHERLANDS.

PUMP, INJECTOR, OR THE LIKE.

Specification of Letters Patent.

Patented Nov. 1, 1910.

To all whom it may concern:

Be it known that I, GERHARD JOAN O'r'ro Donrs -DIKKERS, a subject of theQueen of the Netherlands, residing at Lonneker, near Hengelo, Overysel,in the Kingdom of the Netherlands, have invented certain new and usefulImprovements in Pumps, Injectors, or the Like, of which the following isa specification.

I/Vater supply devices, such as pumps, injectors, or the like, for steamboilers, are generally arranged in a corner of the boilerhouse wherethey do not interfere with the working. Necessary repairs of thesedevices must usually be effected in dark corners, and are inconvenientand expensive as the unscrewing and separation of these apparatus fromthe pipes is very complicated and subject to frequent interruptions. Inorder to overcome these disadvantages, by the present invention theflanges and. pipe connections of the water supply devices (pumps,injectors or similar arrangements) which carry or contain movable partsor parts subject to frequent renewals or exchanges, are arranged on asingle stationary frame. This frame is arranged to be connected, byknown detachable means (such as screw bolts or the like) in such mannerthat they may be easily unfastened, with the other parts of the pumps,injectors, or the like, which contain the remaining parts in constantconnection with the pipes. In order to effect an easy connection, forexample, of the two cylinders of a pump or the like to this frame,connecting pipes are provided in the same, which lead from the pipeconnections arranged on the frame to the ground or packed surface towhich the cyl inders or the like are connected steam or water tight.Further, pi ms or connecting passages are provided in t e connectedparts opposite the openings of the said pipes or connecting passages ofthe frame; the former pipes guide the steam or the water away from theconnecting point or back to the same.

The invention is shown in the accompanying drawing in one form on apump, and in a second form on an injector.

Figure 1 is a side view of a steam pump with the pump cylinder insection, and Fig. 2 is a view of the frame seen from the right side ofFig. 1, the pump cylinder 3 being removed. Fig. 3 is a View of theframe, seen from the left side of Fig. 1, the steam cylinder 2 beingtaken off, while Figs. 4 and 5 are vertical longitudinal sectionsthrough an lnjector.

On the frame 1 (Figs. 1, 2 and 3) the steam cylinder 2 is arranged atone end in the usual manner, and opposite the same, at the other end,the pump cylinder 3. The connection of these two cylinders with theframe 1 is effected in such manner that four T-headed bolts, engage withtheir T-shaped heads 6 or 7 in square recesses or slots 8 of the frameplates 9 and 10. As shown in the drawings, bolts 4 are employed todetachably connect the steam cylinder with frame 1, and longer bolts 5are employed to detachably connect the pump cylinder 3 with said frame.

In pumps as hitherto constructed, the steam supply and outlet pipes werearranged on the cylinder 2, while the water inlet and outlet pipes werearranged on the cylinder 3. The removal of the two cylinders, in orderto execute repairs, was therefore, only possible if the pipe connectionswere loosened.

In the present invention,however, as may.

be seen from the drawing, all the pipe connections are arranged on theframe 1, from whence eonnnunicating passages run to the correspondingcylinders.

\Vhen an air chamber is employed, it may be arranged on the top of therame 1, as may be seen from Figs. 1 and 2, wherein the flanged branch ofthe air chamber is shown. Further a connecting branch or pipe 11 for thesteam inlet is arranged on the frame in such a manner that it isextended on both sides (Fig. 2) permitting the steam su ply pipe to beconnected either on the let or on the right side according to desire,the connection not in useat any time being closed, as usual, by a plate.A passage 12 (Fig. 3) runs from the connecting pipe 11 through the frameand the steam cylinder casin 2, into the slide valve chest 13 (Fig. 1).Zinother passage 14 Figs. 1 and 3) 1s provided for the steam out et orexhaust and also connected up to steam outlet pipes 15 provided at eachside of the frame. By means of this arrangement, it is possible toeasily remove the steam cylinder without affecting the steamsupply oroutlet conduits.

At the bottom of the frame (Figs. 2 and 3) a connecting pipe 16 isprovided on both sides for the water suction pipe. The water is ledthrough the base 1 to the connected whereby the turned cylinder liner22, the

valves 18 and 19 and the other parts may be easily removed after havingloosened the screw bolts 5.

The improvements may be embodied in other apparatusfor instance,injectors connected with steam boilers. The injector shown in Figs. 4and 5 consists of three arts, one of which (23) corresponds to the frame(1 aforesaid) of the pump, this part being provided with the flanges 27,28, 29 and 30, for the pipe connections. Said apparatus further consistsof the casing proper,

24:, and the cap, 25. These three parts are connected with each other bymeans of four bolts 26, so that the cap 25 and the casing 2 1, afterloosening the screws, are easily accessible, or may be separated or bothtaken off from the frame 28.

The connecting pipe flanges 27, 28, 29 and 30 arranged on the frame 23serve as connections for the steam supply conduit, the

suction pipe, the pressure pipe or the drip p p A valve pipe 31 isarranged in the frame, which is made with a bend and an inclined valveseat, adapted to engage with a flap 32 which may be moved upward. Thisvalve and pipe can be easily removed from the frame 23 after removingthe casing 24. As may be seen from the drawings all easily re movableparts, which are known in themselves, such as the steam and waterpassages and mixing and injecting nozzles of the injectors, are arrangedin the casing 24.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

A fluid supply apparatus, consisting of independently detachable membersprovided with inlet and outlet ports and inclosing all the moving partssubject to frequent repair, in combination with a unitary frame providedwith connections for all the inlet and outlet pipes and having the fluidsupply passages connecting the detachable members entirely inclosed insaid frame, and registering with the inlet and outlet ports of thedetachable members.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
